"Not only will these new machines save you time, they use technology that's very similar to the way you pay for everyday items like coffee," said John Strawbridge, Auckland Transport group manager of parking services and compliance.
Motorists will have the choice of machines that use coins, credit cards or cards that have payWave. About 10 per cent machines will only accept cards.
The price of parking will not change and and receipts can be emailed to customers who require them for work purposes.
Strawbridge said the ap had been downloaded 27,000 times.
"Our customers like the start and stop function. It's taken away the need to guess how much time you need to pay for."
The new machines are already used in some private car parks in Auckland and in Tauranga and Christchurch.
